Agenda
- Weigh out what you believe is one mole of three different substances
- Check each other’s masses against the periodic table — who was closest?
- Name it: Molar Mass and Composition — compounds, and percent by mass
- Where percentage composition already tells you something worth knowing
- Practise: Mole Conversions Practice in pairs, one checking the other
Things to do before our next class
- Mole Conversions Practice, questions 1–15, units on every line.
- Journal: the conversion you still have to stop and think about, written out in your own words.
